That model number is a 2018 model, not a 2020 model, though it could have been sold as late as 2020.
The only benefit to this model is that it has user-replaceable (upgradable) RAM and storage. Macs after this generation have non-replaceable RAM and storage (which is why I stopped buying Macs after this generation).
Otherwise, it is a slow, old Mac Mini with an 8th gen mobile Core i5 processor. Remember to bring your own keyboard and mouse, as this model did not come with one originally.
Hello. Asked about the model number vs year.
This model # is correct. It is both 2018 and 2020 year tied to this model # but the specs are the exact same for both years. Both Amazon and the vendor say it’s 2020 so that’s what we go by and the tag on the unit should say 2020.
